I have a Remington 341 Sportsmaster, which I found a few years back at a garage sale and in quite good condition, except the mauser type safety was very loose, and would not hold the firing pin assembly off of the sear. When the safety was released so went the firing pin. Not good. I removed the pin that bears on the cam surface at the back of the bolt and replaced it with the head portion of a 1 3/4 inch finishing nail. The increased diameter of the nail head took up the slack and it is now as tight as a kittens ear. This is a fine shooting rifle, vivid open sights, and has the absolutely best no fail tubular magazine cartridge feeding system.
Which brings up a more interesting story. As a young fellow in the 1950's I found a rifle barrel and action sitting in a pile of cold fire ashes in Saint Augustine Beach, Florida. The stock had been burned off and the muzzle appeared to be rusted shut with sand. Some months later, I began to disassemble it. I wire brushed the parts and found that it was a Remington Model 34. I sawed the barrel off at about 17 inches, ran a brush through it and lo and behold, the rifling was clean and sharp. I filed the barrel end square and crowned the muzzle as described in my favorite, Clyde Baker's Modern Gunsmithing, 2nd edition 1933. With a rat tail file, I cut a new dove tail into the barrel, installed the front sight and filed the rear sight down so that the front bead just sat into the notch. I sawed, carved and rasped out a Mannlicher stock out of a piece of well seasoned 2 x 8 Douglas fir. I fitted this stock to my long reach and cheek position like Clyde told me. A muzzle end barrel clamp was forged from a piece of copper tubing, and a trigger guard was fashioned from a piece of sink drain pipe. The trigger pull was lapped to a fairly firm 1 1/2 to 2 pounds and the right side thumb safety would hold it. I lapped the sides of the cartridge carrier, several inches long, on a new fine corundum stone and polished the cam surfaces. This became an extremely slick bolt action rifle, now carbine. I shot hundreds and perhaps thousands of rounds through this reclaimed piece. My buddy Jim and I shot up a lot of the old abandoned farm dumps out side of Gainesville FL, could hit a bottle pretty good on the fly. This gun came up quick. Probably shot up colloectibles but that's the way it goes. I have attemped to post a pic. Cheers, and regards, firstname.lastname@example.org
